Hi, I have a Babylock Protege serger, which I use only sporadically. I have a basic question. In the middle of a project, the upper looper thread broke. So I unthreaded the serger needles and lower looper-not all the way, but just up to the tension discs. I followed the sequence recommended for my serger-upper looper, lower looper, R needle and left needle. However, the machine will serge for a few inches, then stop serging, and the upper looper thread breaks again. Do I need to completely unthread the machine-up to the spools?
Thanks for any help!

Funny. Similar thing happened to me yesterday afternoon.
I had been working on a fleece top and when I wanted to change from a narrow 3-thread overlock to a wider 3-thread I just couldn't get my threading to work. The needle wasn't catching the upper looper thread. I tinkered and tinkered for about an hour. Finally I told myself that this was just not the time to be fussing with it and that I'd come back the next day and start over.
That's just what I did. Came in and re-threaded (actually changed to a four-thread overlock) and it was beautiful.
Some days are like that and nothing you do will work.
I completely trust my machine so I knew it was just something I wasn't doing right.

I had a problem w/my Husqvarna Viking 936 serger. I unthreaded, re-threaded several times -- problem continued to frustrate the devil outta me. After several hours, reading the manual, actually almost going NUTZ, I changed the needle. Didn't I feel like a real "ditz" -- how simple, and yet how stupid of me not to have thought of this in the beginning!! A lesson well learned for me -- perhaps, I should change the needle first, then try re-threading!! Good luck with yours!!

Thanks , again, to each of you who have replied. Actually there is one question I still have. To rethread, do I have to unthread all the way to the spools, or can I resume the treading AFTER the tension discs,of course following the recommended sequence for my serger?
Thanks.
